RAILWAY-CAR CONSTRUCTION.

' Specification of Letters Patent.

Patented Oct. 8, 1912.

Application filed February 20, 1912. Serial No. 680,001.

To all whom it may concern Be it known that I, OSCAR .OTTERBON, a resident of Butler, in the county of Butler and State of Pennsylvania, have invented a new and useful Im rovement in Railway- Car Construction, of which the following is a specification.

This invention relates to railway-car construction and especially to the construction of steel railway cars.

The object of the invention is to provide an improved construction and. arrangement of parts for securing a panel or sheet of material in position in such manner that it may be readily attached to or detached from its frame, and in which the same is securely held in place without the aid of putty, bolts, screws, nails or other similar means.

The invention comprises the construction and arrangement of parts hereinafter described and claimed.

In the drawings Figure 1 is a cross sectional view showing my invention applied for securing an interior finish panel to the roof or side wall of a sheet metal car; Fig. 2 is a similar view showing another form of the invention; Fig. 3 is a cross sectional view showing one form of my invention applied for securing a pane of glass or other form of panel to a window sash or door frame; Fig. 4 is a detail view showing the manner of insertion of a panel and bead into place; Fig. 5 is a plan view of one end of one form of head or retainer; and Figs. 6, 7, 8 and 9 are cross sectional views showing modified forms of the invention.

In the drawings, 1 represents the frame member to or in which the panel or sheet of material 2 is secured. This may be either a fixed portion of the body of the car, as for example, its roof or side wall, members secured thereto, or a window sash or door frame and the panel may be of metal, glass, or other material. Other uses of the invention and applications of the same will be readily apparent. In Fig. 1 the anel or sheet of material 2 is the interior nish, or ceiling or side panel of the car and is secured to the ,roof'or wall 1, between ribs, beams or boxes 3 forming part of the frame and extending entirely around the edges of the panel. The frame member 1 comprises also a holding member 4 riveted to the box or beam 3, and preferably formed of cold drawn steel, shaped as shown and provided with a groove or channel 5 to receive a bead or retainer 6 for holding the panel or sheet of material 2. The groove or channel 5 is formed between an offset portion 12 of the frame and an abutment or seat 8 against which the anel or sheet of material 2 is pressed or I eld. The bead or retainer 6 is formed of cold drawn steel and may be of various shapes and configurations. In the form shown in Fig. 1 the head or retainer 6 is formed with a curved or arched web or body 6, havin one edge portion turned in the form of at leaf or flange 7 bearing against the outside surface of the panel or sheet of material 2 to press or force it against its seat or abutment 8, as stated. The head or retainer 6 is also provided, at the other side of its web or body portion 6, with an indented locking portion 10 having an inturned flat face 11 seated behind the offset '12 of the frame, and a flat face 13 at right angles thereto and seated on the outer face of the offset. As shown, the ofi'set-is somewhat remote from the seat or abutment 8 in a direction normal to the panel 2. Continuous with the locking portion 10 of the bead or retainer 6 is a keeper flange or spring member 14, to assist in keeping the bead in place and which is arched as shown and in the assembled structure may be seated or engaged either directly under the edge of the panel 2 or,'if preferred, under a rib or flange 9 of the frame and'which is located over the groove or channel 5 and is normal to abutment 8.

The keeper flange or spring 14 may be formed either as a continuation of the locking portion 10,-as shown in Fig. 1, or as a continuation of the flat leaf or flange 7, as shown in Figs. 2 and 6. The panel or sheet of material 2 may be square, rectangular or of other shapes, and in assembling is held in place with its inner surface against the seat or abutment 8 around the edges of the frame, while the beads or retainers 6 are inserted into place. each head or retainer is compresse or flexed, both to bring its flat leaf or flange 7 and locking portion 10 closer together, and also as an entirety from end to end. The ends of the bead or retainer are either mitered to form a close joint at the corners, or are otherwise so formed as to permit of slipping the To accom lish this,

spring member 14 seatedin the channel 5 and under or behind flange 9 and the looking portion 10 in place'behind the offset 12. With either of the, forms shown in Figs. 1 and 2 the bead is easily removed by inserting a suitable tool, as for example, a screw driver or wedge, under the flat face 13 of the which is formed as a continuation of the flat leaf 7, and which engages directly with the edge of the panel or sheet of material 2. In each of the forms shown in Figs. 1 and 2 the head is under tension both before and after being seated in position and any tendency of the panel or sheet of material 2 to become loosened or to lose its position results in merely increasing the tension in the bead and its resistance to displacement of the panel. In the form shown in Fig. 2 the flange 7 presses the panel 2 tightly against the filling block 15- of the frame member 4, while the keeper 14 of the bead presses edgewise against the panel and, in cooperation with the companion keeper at the other edge of the sheet or panel, holds the same securely in position This result is secured by reason of the fact that any edgewise movement of the panel swings the entire bead around the offset 12 as a center and forces the flange 7 more tightly against the panel.

If desired, the offsets 12 on the holding members 4 of the frame may be formed, as shown in Fig. 4, that is, of full height opposite the middle of a panel and decreasing to nothing at each end. With'this form of the invention the bead is flexed or bent from end to end and its ends snapped into place in the corners as before. The body of the bead, however, may then be more easilypushed to its seat behind the offset to secure the bead in place.

In Fig. 3, I have shown the application of that form of my invention shown in Fig. 1, for securing either a pane of glass or a decorative or other panel in a window sash 'or door frame. In this view, the. opposite frame members 1 are either the vertical side stiles of a window sash or the vertical side members of a door frame. This may either be formed solid and of wood or metal,

shaped with a groove 01'. channel 5, as shown,

to receive the bead or retainer 6 for the panel or glass in the same manner as the holding or frame member 4 in Fig. 1. If the frame l isformed of cold drawn steel,

suitable bracing members 16 may be welded or otherwise secured at their ends between the inner and outer portions 17 of the frame to space the same apart and to give rigidity to the structure. In this form of the invention, the groove or channel 5 is formed to provide the oflset 12, behind which is seated the locking portion of head 6, and the abutment or seat 8, as before.

In this construction also, the keeper flange or spring 14 is formed continuous with looking portion 10 and is arched and seated under the edge of the sheet of material orpane of glass 2. Preferably a cap 18, formed-of rubber, cork or other yielding niaterial is interposed between the flat leaf or flange 7, keeper flange 1-4 and seat 8 ofthe frame and the pane of glass 2 to prevent shock or vibration from injury or breaking the pane of glass, since spring or keeper flange 14 of the bead or retainer 6. Yielding flange 14 is engaged directly under the edge of the panel or pane of glass 2 and thus absorbs such shock and Vibration as may be communicated to the glass or panel and tend to cause edgewise movement thereof. The locking portion 10 is also formed with a flat face 13 and with a flat bearing member 19 seated in the bottom of groove or channel 5 and which tends to retain the tension in bead or retainer 6 and prevent flatwise movement of the panel or pane of glass. In thisform of the invention both the keeper flange 14 and bearing member 19 tend to resist displacement of the parts.

In Fig. 7 the yielding flange or spring 14 is formed as a continuation of the locking portion 10 and its edge is engaged under the flange or rib 9 of the frame 1 in the same manner as the keeper 14 shown in Fig. 1.

Fig. 8 shows a construction similar to that of Fig. 6 except that groove or channel 5 is of different shape and the keeper 14 is a continuation of the leaf or'flange 7 instead of the heel 10. This keeper is turned under a fold or flange portion 9 of the metal of the frame corresponding to the rib or flange 9 of 1. 4 l

In some cases where it is inconvenient to form a seat or abutment for the panel on 2, 3 and 6, this may be included as a portion of the bead or retainer itself, and. the bead then also forms a groove or channel for the panel or sheet of material. Such an arrangement is shown in Fig. 9. Here the retainer is formed with the usual leaf or flange 7, and locking portion 10 seated behind the offset 12 of the frame. The spring member 14 is arched and, at its middle portion, is engaged under the edge of the panel or pane of glass 2 and at its other end bears against a shoulder or offset 21 of the frame. Continuous with the keeper 14 is a bearing member, 22, somewhat similar to the head or retainer 6 inappearance, and having a seat or abutment 23 against which the outer side of the panel 2 rests. With this form of the invention it is necessary. to insert a panel into position in the frame with the beads in place on all of its edges. With a square or rectangular panel the arrangement shown in Fig. 5 is convenient for easy insertion of the panel and beads into the frame and looking thereof in place. On two of the opposite sides of the frame, marked A, the, offsets 12 are omitted, and the locking portions 10 of the beads foluthese sides of the frame may also be omitted if desired. On the other opposite sides, marked B, (one onl being shown) the offset 12 is at full heig t at its middle and decreases to nothing at each end. The beads are placed in position on the panel or sheet of material and are bent or distorted in the plane thereof and then slipped past the offsets 12 until the locking portions Y 10 seat behind the same.

The beads shown in Fig, 9 may be either mitered at the corners or if preferred, those marked C in Fig. 5 may be cut ofl" square at their ends and those marked D cut away at their ends, in. the manner shown at 25 in Fig. 5, the cut away ends of beads D embracing and fitting the other beads C.

It will be understood that in all the embodiments of the invention shown, the head or retainer is compressed or placed under tension during the course of its insertion in the frame, and its tensed condition causes the flat leaf or flange 7 to press tightly and firmly against one face of the panel or sheet of material and force and hold the same securely against its seat or abutment. At the same time, the yielding member or keeper 14. tends to resist edgewise movement of the panel and should such movement occur, causes an increase in the tension in the bead and consequently greater clam ing effect on the leaf or flange 7. The loc ing portion 10 is seated behind the offset of the frame and it is almost impossible for'the head to accidentally jump out of its depression or pocket by reas n of abnormal vlbration or 1arofthe structure. Notwithstanding this, it may be easily removed by the use of a suitable tool in the manner stated. In

all cases described the head is securely seated and held. in place in the frame without the against an outer flat face 0 usual threaded screws or bolts. In the usual constructions where a metal frame is provided, the use of screws or bolts requires the tapping of holes of comparatively small diameter in the frame and frequently cause the breaking of expensive taps.

In those forms of the invention where the keeper spring 14 is seated under a fixed portion of the frame, instead of under the edge of the panel itself, as for, example, in Fi 1, 7 and 8, it will be understood that t e keeper member does not act directly in connection with an edge of the panel to sist edgewise movement thereof, but nevert eless is yielding in nature and does so act through leaf or flange 7. In this form of the invention the engagement of the keeper under the flange 9 o the frame prevents transverse rotative movement of the head 6 around the offset 12 as an axis and thus greatly decreases the liability. of flatwise movement of the anel against the flange or leaf 7 and away rom its seat or abutment.

It is of course obvious and will be understood that the invention is not necessarily confined to railway car construction but may be also applied to general buildin con struction or in fact wherever it is esired to removably secure a panel or sheet in position.
